Planets

“Mankind are here because they are the offspring of parents who were first brought here from another planet, and power was given them to propagate their species, and they were commanded to multiply and replenish the earth.”

- Prophet Brigham Young, Journal of Discourses, v. 7, p. 285

“Worlds without number I have created.”

- Pearl of Great Price, Moses 1:33

“Accepting this statement of Joseph Smith relative to our planet in its present state being created or formed from the fragments of a planet which previously existed, one may readily understand how the supposed differences between scientists and believers in revelation have arisen. Scientists have been talking of the earth's strata that were formed in a previously existing planet; they have considered the fossilized flora and fauna imbedded in those strata…. If scientists shall claim that the fossilized remains in the different strata of the earth's crust reveal the fact that in the earlier periods of the earth's existence only the simpler forms of vegetation and animal life are to be found, both forms of life becoming more complex and of a higher type as the earth becomes older, until it is crowned with the presence of man – all that may be allowed. But that this gradation of animal life owes its existence to the processes of evolution is denied…. The claims of evolution as explained by the philosophers [not scientists] of the Darwin school, are contrary to all experience so far as man's knowledge extends.”

"Now regarding Adam: He came here from another planet, an immortalized Being, and brought his wife Eve with him, and by eating of the fruit of this earth, became subject to death and decay. . . was made mortal and subject to death."
